Add some DA & Guilds cards, new strats, and small fixes

New cards: Rebuild, Rogue, Rats, Advisor, Journeyman

New strategies:
- many Rebuild variants, courtesy of SheCantSayNo
- Journeyman-BM
- Advisor-BM, just to demonstrate how terrible it is
- Big Nothing, which does nothing at all, just to test other strategies when they have to end the game on their own
- Lord Bottington, a joke strategy. BM with some rats tossed in

Minor code changes:
- Assume lessc is in the path, rather than specifying it's exact directory. It wasn't in that default directory on my system.
- Don't refresh the page and lose strategy code changes when an error is encountered.
